B. Preparing Calibration Solution

Step 1: Prepare a Container

Choose a clean container with a minimum capacity of 250ml.

7ea14f9d36b2479c5626531ebe04aa83
Step 2: Prepare pH 6.86 Calibration Solution

  • Pour all the pH 6.86 calibration powder into the prepared container.

  • Add 250ml of distilled water to the container, and stir thoroughly with a clean plastic or glass rod until the calibration powder is completely dissolved.

d363f2e0a7643586d343d09664a8f704
Step 3: Prepare pH 4.01 and pH 9.18 Calibration Solutions

Repeat Steps 1 and 2, using the corresponding pH 4.01 and pH 9.18 calibration powders.

05df52ba76864b0b193e1970dc3872f5

Note :

  1. You can use the included 50 ml measuring cup, filling it five times to reach a total of 250 ml of distilled water.

  2. It is recommended to prepare the next calibration solution only after completing the current pH calibration.

  3. Before preparing calibration solutions again, always clean the container and stirring tools with distilled water and dry them thoroughly to ensure no residue remains, as leftover traces may affect calibration results.

  4. Do not use hard materials to wipe the pH probe’s glass electrode, as this can significantly impact its accuracy and lifespan. After cleaning, either shake the electrode dry or gently pat it with a soft, absorbent cloth.

C. Start Calibration

Step 1

Short press the power button to turn on the pH probe, then long press the CAL button to enter calibration mode: The pH icon will flash, and "NIS" will appear at the bottom.

7ef4cbf629e9758ea186cb04892afc1e
Step 2

Rinse the probe with distilled water and shake off excess water. Pour the pH 6.86 calibration solution into a 50 ml measuring cup (about 1/3 full) or the pH probe protective cap (between the MAX-MIN marks).

Step 3

Place the pH probe into the pH 6.86 calibration solution, gently stir a few times, and then let it sit still.

273166d04cb48e7d9f9322fc656e1aa0
Step 4

When the reagent bottle icon in the lower-left corner stays solid and the reading stabilizes, press the CAL button. A smiling face icon will appear, indicating the calibration for this point is complete. The M icon will stay solid, and the next point’s calibration will begin.

da7b5da81d24d2020ec5d8043fff9486
Step 5

Start the second point calibration by repeating Steps 1–4, using the pH 4.01 calibration solution. After calibration, the L icon will stay solid.

0fa580c0f288356c0055ed6c50e48a54
Step 6

Start the third point calibration by repeating Steps 1-4, using the pH 9.18 calibration solution. After calibration, the H icon will stay solid.

0fa580c0f288356c0055ed6c50e48a54

Note:

  1. During calibration, do not turn off the pH probe after completing each calibration point. Otherwise, recalibration will be required.

  2. The manual uses NIST standard calibration solutions. If you wish to use USA standard calibration solutions, you must first switch the calibration solution type in the settings.

  3. After completing the three-point calibration, the pH probe will automatically return to the measurement screen. If only a two-point calibration is needed, press the "Power" button after completing the second calibration point to return to the measurement screen. In this case, only LM or MH will be displayed in the lower-right corner.

4. Measurement

Step 1

Short press the power button to turn on the pH probe, rinse the probe with distilled water, and shake off excess water.

Step 2

Place the pH probe into the solution to be measured, gently stir a few times, then let it sit still. The reagent bottle icon will change from flashing to solid, indicating the reading is stable and the measurement is complete.

da7b5da81d24d2020ec5d8043fff9486

NOTE:

  1. To make readings easier, you can enable the Auto HOLD feature in the settings or manually press the "Calibrate" button to activate HOLD. A short press of the "Calibrate" button will cancel the HOLD function.

  2. When measuring pure water (such as drinking water, RO water, or distilled water), the pH reading may take longer to stabilize (approximately 1–5 minutes). To speed up the measurement without affecting accuracy, you may add a 3 M potassium chloride (KCl) solution to the pure water at a ratio of 1:1000 (1 ml KCl per 1000 ml of pure water).

  3. Do not fully submerge the pH probe in the solution.

Maintenance

Probe Cleaning

(1) Daily Cleaning

Before and after each use, the pH probe must be thoroughly rinsed with distilled water or deionized water to ensure accurate readings.

(2) For Stubborn Stains

Use a specialized electrode cleaner or a mild detergent to soak the probe for 30 minutes. Afterward, gently scrub the probe with a soft brush and rinse thoroughly.

Probe Storage

After using the pH probe, always turn off the power and securely attach the probe protective cap to keep the probe moist. Periodically, add 3–5 drops of potassium chloride solution to the circular sponge inside the protective cap.

9cba6fbac81e4db36dd186f1097e7b0c

NOTE:

  1. Never store the probe in pure water (e.g., distilled water, RO water, or purified water) as it may affect the probe’s lifespan.

  2. If the probe has been stored dry for a long time, soak it in potassium chloride solution for at least 24 hours before recalibrating it.

Probe Replacement

The probe is a consumable item, with a typical lifespan of 1 year, depending on usage frequency and maintenance. It is recommended to replace the probe regularly to ensure optimal performance. Follow these steps for replacement:

Step 1

Remove the probe protective cap, unscrew the nut, and then gently pull the old probe out.

b658b71f23fd558539037ec356ab0494

Step 2

Insert the new probe, ensuring proper alignment with the pins, then screw the probe in tightly.

e0f240ba460931307dca0a7b04b35884

Step 3

Soak the new probe in potassium chloride solution for at least 5 minutes, then calibrate it before use.

NOTE:

  1. Only replace with Vivosun designated probes, as they are not compatible with other brands.

  2. Ensure the nut is tightly screwed to prevent leakage.
